just a thought

so I know this may seem kind of trivial, but I came downstairs this morning at 5:30 and my first impression was that the entire house was awake. I realize that the hall and probably the entryway lights need to be left on, but the whole building was lit up last night. All it takes is if you think you are the last one to leave a room at night, turn off the light. If someone comes back in they can always turn it on again. its an easy way to save energy and it takes almost no effort.
